Assigned to command the Imperial fleet protecting the Relgim Sector, Kolaff reluctantly agreed to Governor Wessex’s order to accompany his wife to Kwenn. He dislikes the fact that he must participate in a trap, preferring to engage an enemy in honorable combat. But he does like the idea of capturing a Rebel traitor. He will go along with Lira Wessex for as long as it serves his own purposes- to achieve a promotion out of the core systems and onto an Imperial Star Destroyer, or even onto a Super Star Destroyer. From such a post, Kolaff knows he could truly distinguish himself in the battle against The Rebel Alliance.

A brilliant tactician and intrepid leader, Kolaff had quickly built a reputation as one of the most competent commanders in the Imperial Navy. He had been known, however, to take his time with certain assignments, savoring the challenge of battle for as long as he could, rather than extinguishing a Rebel threat as quickly and easily as possible This practice eventually became his undoing, as Kolaff was transferred to Relgim to command a fleet of VSDs.

Kolaff is an extremely intelligent, though obsessed, leader who has only one true love in life, the love of battle. He holds no true hatred of the Rebellion, and rather admires their courage. He is smugly confident, sarcastic and believes himself invincible.
